A balloon of air deflated and does 300kj of work to the surrounding air. While deflating the air inside balloon transfers 60kj of energy to the outside of the balloon. What is the total change of the inside the balloon when it deflates?
To start, let's assume that the total change in energy inside the balloon is represented by ΔE. Given that the balloon does 300 kJ of work on the surrounding air and transfers 60 kJ of energy to the outside of the balloon, we can write the equation:
ΔE = -300 kJ + 60 kJ
Simplifying, we find:
ΔE = -240 kJ
Therefore, the total change in energy inside the balloon when it deflates is -240 kJ.
To find the total change in energy inside the balloon when it deflates, we need to consider the work done on the surrounding air and the energy transferred out of the balloon.
Given:
Work done by the balloon on the surrounding air = 300 kJ
Energy transferred out of the balloon = 60 kJ
The total change in energy inside the balloon is the sum of these two quantities, but since the energy transferred out is negative (it's leaving the system), we subtract it:
Total change in energy = Work done on the surrounding air - Energy transferred out
= 300 kJ - 60 kJ
= 240 kJ
Therefore, the total change in energy inside the balloon when it deflates is 240 kJ.
